Unlike the Hutt fighters, the Black Sun ships have three color areas instead of two. The majority of the hull must remain the bare metal "silver" color. The Primary and Secondary colors appear as the red and orange areas below, with red as the Primary and orange as the Secondary. Note that white actually appears as the "silver" base hull color, so don't use that color unless you want to hide part of the design.
According to the official forums, the Black Sun textures are bugged right now, because they don't include all of the details that they should. That's why no patterns can be seen on the wings.
